The earliest baseball collectible depicting Warren Spahn hails from the 1946-49 W603 Sports Exchange series. Subsequently, a popular regionally issued card picturing Spahn was included within the 1947 Tip Top Bread series. Another early Spahn card originates from the 1947 W602 Sports Exchange Minis set. The earliest mainstream card of Spahn was issued in conjunction with the 1948 Bowman issue. Finally, an obscure, tiny card of Spahn was included as part of the R346 baseball series.
